LP87524JRNFRQ1 ( Zamagetsi Zigawo IC Chips Integrated Circuits IC ) LP87524JRNFRQ1

Kufotokozera mwachidule:

LP87524B/J/P-Q1 idapangidwa kuti ikwaniritse zofunikira pakuwongolera mphamvu za mapurosesa aposachedwa ndi mapulatifomu pamapulogalamu osiyanasiyana amagetsi amagalimoto.Chipangizocho chili ndi ma cores anayi otsika a DC-DC, omwe amapangidwa ngati 4 gawo limodzi lotulutsa.Chipangizochi chimayendetsedwa ndi I²C-compatible serial interface ndi kuyatsa ma siginecha.

Kuchita kwa automatic PFM/PWM (AUTO mode) kumakulitsa magwiridwe antchito pamitundu yosiyanasiyana yomwe ilipo.LP87524B/J/P-Q1 imathandizira kuwunika kwamagetsi kwakutali kuti kulipirire kutsika kwa IR pakati pa zotulutsa zowongolera ndi poyambira-katundu (POL) motero kuwongolera kulondola kwamagetsi otulutsa.Kuphatikiza apo wotchi yosinthira imatha kukakamizidwa kunjira ya PWM ndikulumikizidwanso ndi wotchi yakunja kuti muchepetse zosokoneza.

Kusintha Owongolera

Ma switching regulators ndi mtundu wadera womwe umatha kusintha ma voliyumu ndikulowetsa pano kukhala voteji ndi kutulutsa komwe kuli koyenera kwambiri kuwongolera dongosolo lomwe likupangira mphamvu.Mabwalo amtunduwu amadziwikanso kuti otembenuza ndipo ndi abwino kuwongolera mphamvu zomwe zimasamutsidwa pakati pazigawo ziwiri zolumikizanazi kuti zikhalebe ndi voteji yosalekeza yomwe imakhala mkati mwa malire a dera.Iwo ntchito pa apamwamba kwambiri kutembenuka dzuwa kuposazowongolera mzerendikupereka mwayi wowongolera bwino komanso otsika mtengo kwambiri pakuwongolera mphamvu kwanthawi yayitali, komanso kuti nthawi zambiri safuna ma capacitor akunja.

Kodi switching regulators amagwiritsidwa ntchito chiyani?

Zowongolera zamtunduwu nthawi zambiri zimagwiritsidwa ntchito pamagetsi a cell imodzi kapena ma cell ambiri komanso zida zamagetsi zoyendetsedwa ndi batire monga makamera a digito, zotonthoza zamasewera am'manja, owongolera ndi zina zambiri.Ubwino waukulu wogwiritsa ntchito masinthidwe osinthikawa m'malo mowongolera mizere ndikuti amapereka chitetezo chafupipafupi ndikuwonetsetsa chitetezo champhamvu kwambiri komanso chocheperako.Zimakhalanso zabwino kuteteza machitidwe amagetsi ku kutentha kwambiri komanso kuwonongeka kwamakono.

Mitundu ya kusintha owongolera

Step-Up kapena Boost Regulators - Awa ndi mitundu yoyambira kwambiri ya ma switching regulator ndipo amagwiritsidwa ntchito kukulitsa mphamvu yamagetsi.

+ Zosinthira Pansi Pansi kapena Buck-Boost - Amachepetsa kapena kubweza voteji potengera mphamvu yolowera.
